DETACHABLE BUTTON.

Specification of Letters Patent.

Patented Sept. 2,1913.

Application filed November 12, 1912. Serial No. 730,960.

To all calm 1n it may concern.

"ie it known that 1, JOHN F. ZA'K, a citizen of the United States,residing at Chi cage, in the county of Cook and State of Illinois, haveinvented a new and useful Imnrovement in Detachable Buttons, of whichthe following is a specification.

This invention relates to a button and especially to means for securingthe button in position upon the fabric, and the invention is especiallyadapted to military and ornamental buttons, as by means of my iirventiou said buttons can be quickly detached from the fabric for thepurpose of polishing or cleaning, and can be readily reinserted inposition.

The invention consists of the novel features of construction hereinafterdescribed, pointed out in the claims and shown in the accompanyingdrawings, in which,

Figure l is an inner face view of the button, the parts being shown inlocked position. Fig. 2 is a similar view parts being shown in positionready for unlocking. Fig. is a similar view, the button being moved intoposition for disengagement with a locking disk. Fig. 4; is a sectionalview. Fig. 5 is a face view of the locking disk and its ring with thebutton removed. Fig. 6 a perspective view of the button detached.

The invention consists of three parts, a button 1, a disk 2, and a splitring movable about the periphery of the disk, the said disk beingsuitably grooved to receive said ring. The disk is provided with asuitable key-hole slot 4, the head of which is to one side of the centerof the disk and with a notch 5, said notch being in radial alinementwith the slot 4. The button is provided with a bifurcated shank 6, eachmember of which is transversely grooved as shown at 7, said groovedportions being adapted to engage respectively the slot t and the notch5.

In use the shank is inserted through the fabric, the ring is turned sothat the opening in said ring will register with the notch 5 and theshank members of the button are then brought respectively into registrywith the notch and the head of the key-hole slot 4, and the parts aremoved relative to each other so as to bring said shank members into theinner end portions of the notch and slot and the ring is then turned toclose the entrance to the notch 5. \Vith the excep tion of the headportion of the slot t neither the slot nor the notch are of sullieient"width to permit the extreme end portions of the shank members to passtheretlu'ough so that the button cannot become detached except by againturning the ring into the position shown in Figs. 2, 3 and 5 and slidingthe shank members into position for withdrawal.

The disk can be formed of the same material as the button and if desiredcan be in one piece but as shown most clearly in Fig. t, I haveillustrated said disk as being formed of two pieces: an inner faceportion A of bone, celluloid or other suitable unatcrial and a backing Bof metal, these two parts being secured together.

Vhat I claim is 1. The combination with a button having a bifurcatedshank, the end portions of which are transversely grooved, of a diskhaving a radial notch, and a key-hole slot in alinement with said notch,and a split ring movable upon the periphery of the disk.

2. A device of the kind described comprising a button having abifurcated shank, the end portions of which are transversely grooved, adisk having a radial notch to re ccive one of said end portions, and akeyhole slot to receive the other end portion, and a split ringrotatable about said disk and adapted to close the entrance to saidnotch, as and for the purpose set forth.
